Summary of the invention
The utility model, in order to overcome the defect of prior art, devises a kind of sealing insulating polar pole of miniaturization, reduces the height dimension of pole, thus directly reduce the size of high voltage switchgear.
The concrete technical scheme that the utility model is taked is: a kind of sealing insulating polar pole of miniaturization, comprise insulation crust, insulation crust is provided with end of incoming cables, leading-out terminal, the inside of insulation crust one end is provided with arc control device, the inside of the insulation crust other end is provided with insulated tension pole, arc control device and insulated tension pole are coaxially arranged, key is: described end of incoming cables is arranged on the side of insulation crust, leading-out terminal is arranged on the opposite side corresponding with end of incoming cables, fixed contact and moving contact is provided with in arc control device, end of incoming cables to be connected with moving contact by being flexible coupling, moving contact is fixedly connected with insulated tension pole, fixed contact and moving contact are coaxially arranged and fixed contact is fixedly connected with insulation crust, moving contact to be connected with fixed contact by the driving of insulated tension pole or to disconnect, fixed contact is connected with leading-out terminal, leading-out terminal is the fixed contact of tri-station isolating switch.
Described end of incoming cables and leading-out terminal are all arranged on the middle part of insulation crust.
In the sidewall of insulation crust, set up electric conductor, one end of electric conductor is connected with fixed contact, and the other end of electric conductor is connected with leading-out terminal.
The beneficial effects of the utility model are: end of incoming cables and leading-out terminal are all arranged on the sidewall of insulation crust, and the structure distribution of this back-to-back formula, reduces the height dimension of pole, thus reduces the size of high voltage switchgear.And the leading-out terminal of pole is directly used as the fixed contact of tri-station isolating switch, simplify and incorporate pole and overlap and the structure coordinated with tri-station isolating switch, pole is directly as a part for tri-station isolating switch, a kind of knockdown supporting component is formed with tri-station isolating switch, because the fixed contact of tri-station isolating switch is as the leading-out terminal of pole, build with pole and be integrated, when avoiding in the past independent isolating switch combined floodgate, fixed contact is as high-voltage side conductor, for the requirement reaching insulation against ground needs other insulating part as the generation of the situation of support, decrease the consumptive material of epoxy resin.
